Portable XRF Analysis of Occupational Air Filter Samples from Different Workplaces Using Different Samplers: Final Results, Summary and Conclusions11/1/2007 - Peer reviewed journal articlesThis paper concludes a five-year program on research into the use of a portable X-ray fluorescence (XRF) analyzer for analyzing lead in air sampling filters from different industrial environments, including mining, manufacturing and recycling.
10/1/2007 - Peer reviewed journal articlesThe primary goal of this study was to investigate the formation of combustion-generated particles derived from lubrication oil in the absence of fuel-produced soot.
10/1/2007 - Conference papersA paper describing tests conducted in the NIOSH Diesel Laboratory at the Lake Lynn Laboratory experimental mine, a facility developed to allow evaluation of control technologies directly in an underground environment.
8/1/2007 - Conference papersThis paper describes ignition tests on pulverised coal suspensions using a suite of coals of different rank and from different countries of origin and over a range of oxygen and coal concentrations of interest for oxyfuel combustion.
Comparing Measurements of Carbon in Diesel Exhaust Aerosols Using the Aethalometer, NIOSH Method 5040, and SMPS4/1/2007 - Peer reviewed journal articlesThe objective of this paper is to compare the results among (1) a NIOSH published standard to determine the mass of EC and OC on filter samples, (2) the aethalometer, which uses light extinction to measure "black carbon" or BC, and (3) measuring particl...
4/1/2007 - Conference papersThis paper identifies and characterizes nanometer and ultrafine aerosols emitted by diesel engines in the underground environment and evaluates the effects of selected contemporary control technologies.
1/1/2007 - Conference papersThis paper reviews the potential hazards from toxic fumes produced by detonating explosives in surface mining and construction operations. Techniques to protect workers and the public from the hazards of explosive-related toxic fumes are discussed.
6/1/2006 - Conference papersThis paper focuses on the flow patterns within the gob under three different ventilation systems: one-entry and two-entry bleederless systems, as well as a three-entry bleeder system.
6/1/2006 - Book chaptersThis chapter provides guidelines for determining the gas content of coalbeds, estimating the gas-in-place, and predicting gas flow and emissions before and during coal mining operations.
The Effects of Water Spray Placement for Controlling Respirable Dust and Face Methane Concentrations4/1/2006 - Peer reviewed journal articlesA series of laboratory evaluations examined the impact of water spray pressure, curtain setback distance, and external and underboom spray use for controlling respirable dust levels and sulfur hexafluoride tracer gas concentrations around a continuous m...
